class Harmonic { public static void main(String…s) { int n,i; float sum=0; n=Integer.parseInt(s[0]); for(i=1;i<=n;i++) { sum=sum+(float)1/i; } System.out.println(“nSum=”+sum); } }
Here you will get program for fibonacci series in Java. It is a series in which next term is obtained by adding previous two terms. A fibonacci series will look like 0 1 1 2 3 5 8 13 21 34 . . . . Program for Fibonacci Series in Java package com; import java.util.Scanner; class …
Here you will learn how to reverse number in java with a program example. For example given number is 1478 then its reverse will be 8741. Program to Reverse Number in Java package com; import java.util.Scanner; class Reverse { public static void main(String…s) { int n,rev=0,i; Scanner sc = new Scanner(System.in); System.out.println(“Enter any number: “); …
Here you will get program for factorial in java. We can find factorial of any number by multiplying it with all the numbers below it. For example, factorial of 4 is 4*3*2*1 = 24. Program for Factorial in Java package com; import java.util.Scanner; class Factorial { public static void main(String…s) { int n,fac=1,i; Scanner sc …
Here you will learn about number palindrome in java. A number is called palindrome if it is equal to its reverse. For example 1221 is a palindrome while 1234 is not palindrome. Below I have shared the java program to check given number is palindrome or not. Also Read: String Palindrome in Java Program …
class Days { public static void main(String…s) { int n,m,d; n=Integer.parseInt(s[0]); m=n/30; d=n%30; System.out.println(n+” days“+” = “+m+” months “+”and “+d+” days”); } }
class Swap { public static void main(String…s) { int a,b; a=Integer.parseInt(s[0]); b=Integer.parseInt(s[1]); System.out.println(“nBefore Swap:n”+”a=”+a+”tb=”+b); a=a+b; b=a-b; a=a-b; System.out.println(“nAfter Swap:n”+”a=”+a+”tb=”+b); } }
